Unable to browse to remote.domain.com from the external network only.
Posted on 2012-03-18
We are presently running Windows SBS 2011. We are port forwaring 443 from an external IP, which we are performing 1to1 NAT, to the server on an internal IP. Up until today it has worked great.
Today, we installed all the windows critical updates and we installed AVG anti-virus.
We are able to, from the LAN, browse to https://remote.domain.com and get the web login screen. When we login from the Internet, we are getting the error from IE, The page you are looking for could not be found.
We checked DNS, it is resolving correctly.
We checked the port forward, it is working fine on 443 and 3389 for RDP. RDP is working great.
We have gone to the application events and we do not see denials.
Thank you ahead of time for your feedback!
